A stunning ecommerce site

I need an ecommerce site that can be viewed on mobile devices (iphone and ipads) aswell as pc's. The site will be retailing furniture: Dining, Bedroom Living/Occasional Etc. I need to be able to change the stock/pictures, prices and descriptions at a moments notice so need to be able to manage these things myself. I have a domain name and am using google for mail services at the moment. The product numbers will vary constantly so I need to be able to add pages and remove them etc as and when required. I'm not interested in paying anyone a fortune for a standard template from 1-1 website builders!! Please send details of real portfolios thanks Greg
